DeweyDecimal

• java.lang.Object

Fields Summary
private int[]	components Array of components that make up DeweyDecimal

Constructors Summary
public DeweyDecimal(int[] components) Construct a DeweyDecimal from an array of integer components. param components an array of integer components. this.components = new int[components.length]; for (int i = 0; i < components.length; i++) { this.components[i] = components[i]; }
public DeweyDecimal(String string) Construct a DeweyDecimal from string in DeweyDecimal format. param string the string in dewey decimal format exception NumberFormatException if string is malformed final StringTokenizer tokenizer = new StringTokenizer(string, ".", true); final int size = tokenizer.countTokens(); components = new int[ (size + 1) / 2 ]; for (int i = 0; i < components.length; i++) { final String component = tokenizer.nextToken(); if (component.equals("")) { throw new NumberFormatException("Empty component in string"); } components[ i ] = Integer.parseInt(component); //Strip '.' token if (tokenizer.hasMoreTokens()) { tokenizer.nextToken(); //If it ended in a dot, throw an exception if (!tokenizer.hasMoreTokens()) { throw new NumberFormatException("DeweyDecimal ended in a '.'"); } } }

Methods Summary
public int	get(int index) Return the component at specified index. param index the index of components return the value of component at index return components[ index ];
public int	getSize() Return number of components in DeweyDecimal. return the number of components in dewey decimal return components.length;
public boolean	isEqual(org.apache.tools.ant.util.DeweyDecimal other) Return true if this DeweyDecimal is equal to the other DeweyDecimal. param other the other DeweyDecimal return true if equal to other DeweyDecimal, false otherwise final int max = Math.max(other.components.length, components.length); for (int i = 0; i < max; i++) { final int component1 = (i < components.length) ? components[ i ] : 0; final int component2 = (i < other.components.length) ? other.components[ i ] : 0; if (component2 != component1) { return false; } } return true; // Exact match
public boolean	isGreaterThan(org.apache.tools.ant.util.DeweyDecimal other) Return true if this DeweyDecimal is greater than the other DeweyDecimal. param other the other DeweyDecimal return true if greater than other DeweyDecimal, false otherwise final int max = Math.max(other.components.length, components.length); for (int i = 0; i < max; i++) { final int component1 = (i < components.length) ? components[ i ] : 0; final int component2 = (i < other.components.length) ? other.components[ i ] : 0; if (component2 > component1) { return false; } if (component2 < component1) { return true; } } return false; // Exact match
public boolean	isGreaterThanOrEqual(org.apache.tools.ant.util.DeweyDecimal other) Return true if this DeweyDecimal is greater than or equal to the other DeweyDecimal. param other the other DeweyDecimal return true if greater than or equal to other DeweyDecimal, false otherwise final int max = Math.max(other.components.length, components.length); for (int i = 0; i < max; i++) { final int component1 = (i < components.length) ? components[ i ] : 0; final int component2 = (i < other.components.length) ? other.components[ i ] : 0; if (component2 > component1) { return false; } if (component2 < component1) { return true; } } return true; // Exact match
public boolean	isLessThan(org.apache.tools.ant.util.DeweyDecimal other) Return true if this DeweyDecimal is less than the other DeweyDecimal. param other the other DeweyDecimal return true if less than other DeweyDecimal, false otherwise return !isGreaterThanOrEqual(other);
public boolean	isLessThanOrEqual(org.apache.tools.ant.util.DeweyDecimal other) Return true if this DeweyDecimal is less than or equal to the other DeweyDecimal. param other the other DeweyDecimal return true if less than or equal to other DeweyDecimal, false otherwise return !isGreaterThan(other);
public java.lang.String	toString() Return string representation of DeweyDecimal. return the string representation of DeweyDecimal. final StringBuffer sb = new StringBuffer(); for (int i = 0; i < components.length; i++) { if (i != 0) { sb.append('."); } sb.append(components[ i ]); } return sb.toString();
