Constructor Detail

OrNode

public OrNode(List<ExprNode> childList)

Creates a OrNode using a logical operator and a list of children.

Parameters:

childList - the child nodes under this branch node.

OrNode

public OrNode(ExprNode... childList)

Creates a OrNode using a logical operator and a list of children.

Parameters:

childList - the child nodes under this branch node.

OrNode

public OrNode()

Creates an empty OrNode

Method Detail

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 StringBuilder printRefinementToBuffer(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:

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

See Also:

ExprNode.printRefinementToBuffer(StringBuilder)

toString

public 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

See Also:

Object.toString()

hashCode

public int hashCode()

Overrides:

hashCode in class BranchNode

Returns:

the instance's hash code

See Also:

Object.hashCode()

equals

public boolean equals(Object other)

Overrides:

equals in class BranchNode

Returns:

true if both objects are equal

Object.equals(java.lang.Object)
