Constructor Summary

NotNode()
Creates an empty NotNode

NotNode(ExprNode child)
Creates a NotNode using a logical NOT operator and the given child.

Constructor Detail

NotNode

public NotNode(java.util.List<ExprNode> childList)

Creates a NotNode using a logical NOT operator and a list of children. A Not node could contain only one child

Parameters:

childList - the child nodes under this branch node.

NotNode

public NotNode(ExprNode child)

Creates a NotNode using a logical NOT operator and the given child.

Parameters:

child - the child node under this branch node.

NotNode

public NotNode()

Creates an empty NotNode

Method Detail

clone

public ExprNode clone()

Clone the Node

Specified by:

clone in interface ExprNode

Overrides:

clone in class BranchNode

Returns:

the clone

addNode

public void addNode(ExprNode node)

Adds a child node to this NOT node node

Overrides:

addNode in class BranchNode

Parameters:

node - the child expression to add to this NOT node

addNodeToHead

public void addNodeToHead(ExprNode node)

Adds a child node to this NOT node at the head rather than the tail.

Overrides:

addNodeToHead in class BranchNode

Parameters:

node - the child expression to add to this branch node

setChildren

public void setChildren(java.util.List<ExprNode> childList)

Sets the list of children under this node.

Overrides:

setChildren in class BranchNode

Parameters:

childList - the list of children to set.

getOperator

public AssertionType getOperator()

Gets the operator for this branch node.

Returns:

the operator constant.

isDisjunction

public boolean isDisjunction()

Tests whether or not this node is a disjunction (a OR'ed branch).

Returns:

true if the operation is a OR, false otherwise.

isConjunction

public boolean isConjunction()

Tests whether or not this node is a conjunction (a AND'ed branch).

Returns:

true if the operation is a AND, false otherwise.

isNegation

public boolean isNegation()

Tests whether or not this node is a negation (a NOT'ed branch).

Returns:

true if the operation is a NOT, false otherwise.

printRefinementToBuffer

public java.lang.StringBuilder printRefinementToBuffer(java.lang.StringBuilder buf)

Description copied from class: AbstractExprNode

Default implementation for this method : just throw an exception.

Specified by:

printRefinementToBuffer in interface ExprNode

Overrides:

printRefinementToBuffer in class AbstractExprNode

Parameters:

buf - the buffer to append to.

Returns:

The buffer in which the refinement has been appended

Throws:

java.lang.UnsupportedOperationException - if this node isn't a part of a refinement.

See Also:

ExprNode#printRefinementToBuffer(StringBuffer)

toString

public java.lang.String toString()

Gets the recursive prefix string represent of the filter from this node down.

Overrides:

toString in class AbstractExprNode

Returns:

A string representing the AndNode

Object.toString()
