Attributes2Impl

• java.lang.Object
  • org.xml.sax.helpers.AttributesImpl

Fields Summary
private boolean[]	declared
private boolean[]	specified

Constructors Summary
public Attributes2Impl() Construct a new, empty Attributes2Impl object.
public Attributes2Impl(Attributes atts) Copy an existing Attributes or Attributes2 object. If the object implements Attributes2, values of the specified and declared flags for each attribute are copied. Otherwise the flag values are defaulted to assume no DTD was used, unless there is evidence to the contrary (such as attributes with type other than CDATA, which must have been declared). This constructor is especially useful inside a {@link org.xml.sax.ContentHandler#startElement startElement} event. param atts The existing Attributes object. super (atts);

Methods Summary
public void	addAttribute(java.lang.String uri, java.lang.String localName, java.lang.String qName, java.lang.String type, java.lang.String value) Add an attribute to the end of the list, setting its "specified" flag to true. To set that flag's value to false, use {@link #setSpecified}. Unless the attribute type is CDATA, this attribute is marked as being declared in the DTD. To set that flag's value to true for CDATA attributes, use {@link #setDeclared}. see AttributesImpl#addAttribute super.addAttribute (uri, localName, qName, type, value); int length = getLength (); if (length < specified.length) { boolean newFlags []; newFlags = new boolean [length]; System.arraycopy (declared, 0, newFlags, 0, declared.length); declared = newFlags; newFlags = new boolean [length]; System.arraycopy (specified, 0, newFlags, 0, specified.length); specified = newFlags; } specified [length - 1] = true; declared [length - 1] = !"CDATA".equals (type);
public boolean	isDeclared(int index) Returns the current value of the attribute's "declared" flag. if (index < 0 || index >= getLength ()) throw new ArrayIndexOutOfBoundsException ( "No attribute at index: " + index); return declared [index];
public boolean	isDeclared(java.lang.String uri, java.lang.String localName) Returns the current value of the attribute's "declared" flag. int index = getIndex (uri, localName); if (index < 0) throw new IllegalArgumentException ( "No such attribute: local=" + localName + ", namespace=" + uri); return declared [index];
public boolean	isDeclared(java.lang.String qName) Returns the current value of the attribute's "declared" flag. int index = getIndex (qName); if (index < 0) throw new IllegalArgumentException ( "No such attribute: " + qName); return declared [index];
public boolean	isSpecified(int index) Returns the current value of an attribute's "specified" flag. param index The attribute index (zero-based). return current flag value exception java.lang.ArrayIndexOutOfBoundsException When the supplied index does not identify an attribute. if (index < 0 || index >= getLength ()) throw new ArrayIndexOutOfBoundsException ( "No attribute at index: " + index); return specified [index];
public boolean	isSpecified(java.lang.String uri, java.lang.String localName) Returns the current value of an attribute's "specified" flag. param uri The Namespace URI, or the empty string if the name has no Namespace URI. param localName The attribute's local name. return current flag value exception java.lang.IllegalArgumentException When the supplied names do not identify an attribute. int index = getIndex (uri, localName); if (index < 0) throw new IllegalArgumentException ( "No such attribute: local=" + localName + ", namespace=" + uri); return specified [index];
public boolean	isSpecified(java.lang.String qName) Returns the current value of an attribute's "specified" flag. param qName The XML qualified (prefixed) name. return current flag value exception java.lang.IllegalArgumentException When the supplied name does not identify an attribute. int index = getIndex (qName); if (index < 0) throw new IllegalArgumentException ( "No such attribute: " + qName); return specified [index];
public void	removeAttribute(int index) int origMax = getLength () - 1; super.removeAttribute (index); if (index != origMax) { System.arraycopy (declared, index + 1, declared, index, origMax - index); System.arraycopy (specified, index + 1, specified, index, origMax - index); }
public void	setAttributes(org.xml.sax.Attributes atts) Copy an entire Attributes object. The "specified" flags are assigned as true, and "declared" flags as false (except when an attribute's type is not CDATA), unless the object is an Attributes2 object. In that case those flag values are all copied. see AttributesImpl#setAttributes int length = atts.getLength (); super.setAttributes (atts); declared = new boolean [length]; specified = new boolean [length]; if (atts instanceof Attributes2) { Attributes2 a2 = (Attributes2) atts; for (int i = 0; i < length; i++) { declared [i] = a2.isDeclared (i); specified [i] = a2.isSpecified (i); } } else { for (int i = 0; i < length; i++) { declared [i] = !"CDATA".equals (atts.getType (i)); specified [i] = true; } }
public void	setDeclared(int index, boolean value) Assign a value to the "declared" flag of a specific attribute. This is normally needed only for attributes of type CDATA, including attributes whose type is changed to or from CDATA. param index The index of the attribute (zero-based). param value The desired flag value. exception java.lang.ArrayIndexOutOfBoundsException When the supplied index does not identify an attribute. see #setType if (index < 0 || index >= getLength ()) throw new ArrayIndexOutOfBoundsException ( "No attribute at index: " + index); declared [index] = value;
public void	setSpecified(int index, boolean value) Assign a value to the "specified" flag of a specific attribute. This is the only way this flag can be cleared, except clearing by initialization with the copy constructor. param index The index of the attribute (zero-based). param value The desired flag value. exception java.lang.ArrayIndexOutOfBoundsException When the supplied index does not identify an attribute. if (index < 0 || index >= getLength ()) throw new ArrayIndexOutOfBoundsException ( "No attribute at index: " + index); specified [index] = value;
