public HKern(DocumentNode ownerDocument) Constructor. param ownerDocument this element's owner DocumentNode super(ownerDocument);

Methods Summary
public java.lang.String[]	getG1() return this node's matching glyphs names for the first glyph return g1;
public java.lang.String[]	getG2() return this node's matching glyph names for the second glyph return g2;
public float	getK() return this kerning entry's advance. return k;
public java.lang.String	getLocalName() return the SVGConstants.SVG_HKERN_TAG value return SVGConstants.SVG_HKERN_TAG;
public java.lang.String[]	getRequiredTraits() return an array of traits that are required by this element. return REQUIRED_TRAITS;
public java.lang.String	getTraitImpl(java.lang.String name) HKern handles the u1, u2, g1, g2 and k traits. param name the requested trait name (e.g., "horiz-adv-x") return the trait's value, as a string. throws DOMException with error code NOT_SUPPORTED_ERROR if the requested trait is not supported on this element or null. throws DOMException with error code TYPE_MISMATCH_ERR if requested trait's computed value cannot be converted to a String (SVG Tiny only). if (SVGConstants.SVG_U1_ATTRIBUTE == name) { return unicodeRangeToStringTrait(u1); } else if (SVGConstants.SVG_U2_ATTRIBUTE == name) { return unicodeRangeToStringTrait(u2); } else if (SVGConstants.SVG_G1_ATTRIBUTE == name) { return toStringTrait(g1); } else if (SVGConstants.SVG_G2_ATTRIBUTE == name) { return toStringTrait(g2); } else if (SVGConstants.SVG_K_ATTRIBUTE == name) { return Float.toString(k); } else { return super.getTraitImpl(name); }
public int[][]	getU1() return this node's matching unicode ranges for the first glyph return u1;
public int[][]	getU2() return this node's matching unicode ranges for the second glyph return u2;
boolean	matches(Glyph glyph, int[][] u, java.lang.String[] g) Checks if the input glyph is a match for the input set of unicode ranges and/or glyph names. param glyph the glyph to match. param u the set of unicode ranges param g the set of glyph names. return true if there is a match. String gu = glyph.getUnicode(); String[] gg = glyph.getGlyphName(); if (u != null && gu != null && gu.length() == 1) { char c = gu.charAt(0); for (int i = 0; i < u.length; i++) { if (c >= u[i][0] && c <= u[i][1]) { return true; } } } if (gg != null && g != null) { for (int i = 0; i < gg.length; i++) { String gn = gg[i]; for (int j = 0; j < g.length; j++) { if (g[j].equals(gn)) { return true; } } } } return false;
public boolean	matchesFirst(Glyph g) Checks if the input glyph is a match for u1 or g1. param g the glyph to match. return true if the unicode range or glyph name of the input Glyph matches the kerning's u1 or g1 setting. return matches(g, u1, g1);
public boolean	matchesSecond(Glyph g) Checks if the input glyph is a match for u2 or g2. param g the glyph to match. return true if the unicode range or glyph name of the input Glyph matches the kerning's u2 or g2 setting. return matches(g, u2, g2);

public void	setG2(java.lang.String[] g2) Sets this kerning entry second glyph names matches. param g2 the list of matching names. if (equal(g2, this.g2)) { return; } modifyingNode(); this.g2 = g2; modifiedNode();
public void	setK(float k) Sets this kernixng entry's advance. param k the new kerning advance if (this.k == k) { return; } modifyingNode(); this.k = k; modifiedNode();
public void	setTraitImpl(java.lang.String name, java.lang.String value) HKern handles the u1, u2, g1, g2 and k traits. param name the trait's name (e.g., "units-per-em") param value the new trait string value (e.g., "1000") throws DOMException with error code NOT_SUPPORTED_ERROR if the requested trait is not supported on this element or null. throws DOMException with error code TYPE_MISMATCH_ERR if the requested trait's value cannot be specified as a String throws DOMException with error code INVALID_ACCESS_ERR if the input value is an invalid value for the given trait or null. throws DOMException with error code NO_MODIFICATION_ALLOWED_ERR: if attempt is made to change readonly trait. if (SVGConstants.SVG_U1_ATTRIBUTE == name) { checkWriteLoading(name); setU1(parseUnicodeRangeTrait(name, value)); } else if (SVGConstants.SVG_U2_ATTRIBUTE == name) { checkWriteLoading(name); setU2(parseUnicodeRangeTrait(name, value)); } else if (SVGConstants.SVG_G1_ATTRIBUTE == name) { checkWriteLoading(name); setG1(parseStringArrayTrait(name, value, SVGConstants.COMMA_STR)); } else if (SVGConstants.SVG_G2_ATTRIBUTE == name) { checkWriteLoading(name); setG2(parseStringArrayTrait(name, value, SVGConstants.COMMA_STR)); } else if (SVGConstants.SVG_K_ATTRIBUTE == name) { checkWriteLoading(name); setK(parseFloatTrait(name, value)); } else { super.setTraitImpl(name, value); }
public void	setU1(int[][] u1) Sets this kerning entry's first match param u1 the new matching unicode ranges. throws IllegalArgumentException if the input array has an entry which is not of length 2. if (u1 != null) { for (int i = 0; i < u1.length; i++) { if (u1[i] == null || u1[i].length != 2) { throw new IllegalArgumentException(); } } } if (equal(u1, this.u1)) { return; } modifyingNode(); this.u1 = u1; modifiedNode();

boolean	supportsTrait(java.lang.String traitName) HKern handles the u1, u2, g1, g2 and k traits. param traitName the name of the trait which the element may support. return true if this element supports the given trait in one of the trait accessor methods. if (SVGConstants.SVG_U1_ATTRIBUTE == traitName || SVGConstants.SVG_U2_ATTRIBUTE == traitName || SVGConstants.SVG_G1_ATTRIBUTE == traitName || SVGConstants.SVG_G2_ATTRIBUTE == traitName || SVGConstants.SVG_K_ATTRIBUTE == traitName) { return true; } return super.supportsTrait(traitName);
