Interface Context

All Known Implementing Classes:

DefaultContext

public interface Context

Interface for the execution context.

You have for example node values (see getEvalValue(FieldId)), failed nodes (see getEvalFalse()), etc.

Method Summary

Modifier and Type	Method and Description
void	addEvalFalse(Metadata metadata) Adds the given node that evaluates to false.
void	addEvalTrue(Metadata metadata) Adds the given node that evaluates to true.
void	addEvalValue(FieldId id, java.lang.Object value) Adds the given evaluation value for the given field id.
void	addSetValue(FieldId id, java.lang.Object value) Adds the set value for the given field id.
java.util.List<Metadata>	getEvalFalse() Returns the list of nodes that evaluates to false.
java.util.List<Metadata>	getEvalTrue() Returns the list of nodes that evaluates to true.
java.lang.Object	getEvalValue(FieldId id) Return the evaluation value for this field id.
Metadata	getRootMetadata() Returns the root node of the syntax tree.
boolean	isEvalFalse(Metadata metadata) Returns true if the given node evaluation is false.
boolean	isEvalTrue(Metadata metadata) Returns true if the given node evaluation is true.
boolean	isShortCircuit() Returns true if the evaluation short-circuit is activated, which will evaluate logical expression like java.

Method Detail

getRootMetadata

Metadata getRootMetadata()

Returns the root node of the syntax tree.

Returns:

the metadata

isShortCircuit

boolean isShortCircuit()

Returns true if the evaluation short-circuit is activated, which will evaluate logical expression like java. Activated by default.

Returns:

true if activated

addEvalFalse

void addEvalFalse(Metadata metadata)

Adds the given node that evaluates to false.

Parameters:

metadata - the metadata

addEvalTrue

void addEvalTrue(Metadata metadata)

Adds the given node that evaluates to true.

Parameters:

metadata - the metadata

addEvalValue

void addEvalValue(FieldId id,
                  java.lang.Object value)

Adds the given evaluation value for the given field id.

Parameters:

id - the id

value - the value

addSetValue

void addSetValue(FieldId id,
                 java.lang.Object value)

Adds the set value for the given field id.

Parameters:

id - the id

value - the value

getEvalValue

java.lang.Object getEvalValue(FieldId id)

Return the evaluation value for this field id.

Parameters:

id - the id

Returns:

the value

isEvalTrue

boolean isEvalTrue(Metadata metadata)

Returns true if the given node evaluation is true.

Parameters:

metadata - the metadata

Returns:

true if eval is true

isEvalFalse

boolean isEvalFalse(Metadata metadata)

Returns true if the given node evaluation is false.

Parameters:

metadata - the metadata

Returns:

true if eval is false

getEvalTrue

java.util.List<Metadata> getEvalTrue()

Returns the list of nodes that evaluates to true.

Returns:

the eval list

getEvalFalse

java.util.List<Metadata> getEvalFalse()

Returns the list of nodes that evaluates to false.

Returns:

the eval list
