Constructor Summary

ScriptCommonEvaluations()

Method Summary

protected java.lang.String	doPad(java.lang.String str, int left, int right) adds white space to the left and right of the string passed, or returns the string if either pad numbers are negative.
static java.lang.Object	doRegex(int function, java.lang.String arg1, java.lang.String arg2, java.lang.String arg3) execute a regEx method
protected static boolean	doRegexInit() Use reflection to initialize the regular expression Java methods (1.4 only)
boolean	evaluateFunction(ScriptInfo info, java.lang.Object[] args, ExecutionContext cxt) Evaluate standard functions.
void	load(ScriptRegistrator reg) Initializes configuration hashtable.
protected static java.lang.String	stringFill(java.lang.String str, java.lang.String fill, long len, boolean isRight) This function either right or left fills the given string with the specified character up the desired length.
protected static java.lang.String	stringReplace(java.lang.String str, java.lang.String fromStr, java.lang.String toStr) This function works on the first parameter replacing all occurrences of fromStr with toStr.
protected static java.lang.String	stringReplaceIgnoreCase(java.lang.String str, java.lang.String fromStr, java.lang.String toStr)

COMMON_FUNCTIONS

public static final java.lang.String[] COMMON_FUNCTIONS

List of functions that are supported and configuration data for each function.

COMMON_FUNCTIONS_CONFIG

public static final int[][] COMMON_FUNCTIONS_CONFIG

Configuration data for functions. This list must align with the "COMMON_FUNCTIONS" list. In order the values are function id, Number of arguments", "First argument type", "Second argument type", "Return Type". Return type has the following possible values: 0 generic object 1 boolean 2 integer 3 double. The value "-1" means the value is unspecified.
