Method Detail

getExpressionString

public final java.lang.String getExpressionString()

Builds the expression outer string form. This methods makes a StringBuilder and calls recursively appendExpressionString() on each child node.

Specified by:

getExpressionString in interface IExpression

Returns:

String

appendExpressionString

protected abstract void appendExpressionString(java.lang.StringBuilder builder)

Recursive method to build an expression string form.

Parameters:

builder -

getValuePattern

public final java.lang.String getValuePattern()

Builds the returned values regular expression. This methods makes a StringBuilder and calls recursively appendValuePattern() on each child node.

Specified by:

getValuePattern in interface IExpression

Returns:

String

appendValuePattern

protected abstract void appendValuePattern(java.lang.StringBuilder builder)

Recursive method to build the returned values regular expression. This is used for advanced validation.

Parameters:

builder -

toString

public final java.lang.String toString()

Overrides:

toString in class java.lang.Object

getPosition

public final int getPosition()

Returns the node's start position (character) in the original expression string.

Specified by:

getPosition in interface IExprNode
