final class DefaultStringExpression

extends StringExpression

The default implementation of a StringExpression that wraps a string.

Since:

2.3

Version:

Field Summary

private AbstractExpression	owningExpression The Expression from where the text value comes.
private java.lang.String	value The wrapped string value.

Constructor Summary

DefaultStringExpression(AbstractExpression owningExpression, java.lang.String value)
Creates a new DefaultStringExpression.

Method Summary

java.util.ListIterator<StringExpression>	orderedChildren() Creates a list representing this expression and its children.
(package private) void	populatePosition(QueryPosition queryPosition, int position) Retrieves the StringExpression located at the given position using the actual query, which may have extra whitespace.
java.lang.String	toActualText() Generates a string representation of this StringExpression, which needs to include any characters that are considered virtual, i.e. that was parsed when the query is incomplete and is needed for functionality like content assist.
java.lang.String	toParsedText() Returns a string representation of this StringExpression and its children.

Constructor Detail

DefaultStringExpression

DefaultStringExpression(AbstractExpression owningExpression,
                        java.lang.String value)

Creates a new DefaultStringExpression.

Parameters:

owningExpression - The Expression from where the text value comes

value - The string value to wrap with this StringExpression

Method Detail

orderedChildren

public java.util.ListIterator<StringExpression> orderedChildren()

Creates a list representing this expression and its children. In order to add every piece of the expression, #addChildrenTo(Collection) is called.

Specified by:

orderedChildren in class StringExpression

Returns:

The StringExpressions representing this Expression

populatePosition

void populatePosition(QueryPosition queryPosition,
                      int position)

Retrieves the StringExpression located at the given position using the actual query, which may have extra whitespace.

Specified by:

populatePosition in class StringExpression

position - The array has one element and is the position of the StringExpression to retrieve

toActualText

public java.lang.String toActualText()

Generates a string representation of this StringExpression, which needs to include any characters that are considered virtual, i.e. that was parsed when the query is incomplete and is needed for functionality like content assist.

Specified by:

toActualText in class StringExpression

Returns:

The string representation of this StringExpression

toParsedText

public java.lang.String toParsedText()

Returns a string representation of this StringExpression and its children. The expression should contain whitespace even if the beautified version would not have any. For instance, "SELECT e " should be returned where Expression#toText() would return "SELECT e".

Specified by:

toParsedText in class StringExpression

Returns:

The string representation of this StringExpression

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
