Class Param2containmentMatch

java.lang.Object

org.eclipse.incquery.runtime.api.impl.BasePatternMatch

org.eclipse.incquery.viewers.runtime.model.patterns.Param2containmentMatch

All Implemented Interfaces:

java.lang.Cloneable, IPatternMatch

public abstract class Param2containmentMatch
extends BasePatternMatch

Pattern-specific match representation of the org.eclipse.incquery.viewers.runtime.model.patterns.param2containment pattern, to be used in conjunction with Param2containmentMatcher.

Class fields correspond to parameters of the pattern. Fields with value null are considered unassigned. Each instance is a (possibly partial) substitution of pattern parameters, usable to represent a match of the pattern in the result of a query, or to specify the bound (fixed) input parameters when issuing a query.

Method Detail

get

public java.lang.Object get(java.lang.String parameterName)

Description copied from interface: IPatternMatch

Returns the value of the parameter with the given name, or null if name is invalid.

getSource

public java.lang.Object getSource()

getTarget

public java.lang.Object getTarget()

getTrace

public Trace getTrace()

getContainment

public Containment getContainment()

set

public boolean set(java.lang.String parameterName,
                   java.lang.Object newValue)

Description copied from interface: IPatternMatch

Sets the parameter with the given name to the given value.

Works only if match is mutable. See IPatternMatch.isMutable().

setSource

public void setSource(java.lang.Object pSource)

setTarget

public void setTarget(java.lang.Object pTarget)

setTrace

public void setTrace(Trace pTrace)

setContainment

public void setContainment(Containment pContainment)

patternName

public java.lang.String patternName()

Description copied from interface: IPatternMatch

Identifies the name of the pattern for which this is a match.

Specified by:

patternName in interface IPatternMatch

Overrides:

patternName in class BasePatternMatch

parameterNames

public java.util.List<java.lang.String> parameterNames()

Description copied from interface: IPatternMatch

Returns the list of symbolic parameter names.

Specified by:

parameterNames in interface IPatternMatch

Overrides:

parameterNames in class BasePatternMatch

toArray

public java.lang.Object[] toArray()

Description copied from interface: IPatternMatch

Converts the match to an array representation, with each pattern parameter at their respective position. In case of a partial match, unsubstituted parameters will be represented as null elements in the array.

Returns:

a newly constructed array containing each parameter substitution of the match in order.

toImmutable

public Param2containmentMatch toImmutable()

Description copied from interface: IPatternMatch

Takes an immutable snapshot of this match.

Returns:

the match itself in case of immutable matches, an immutable copy in case of mutable ones.

prettyPrint

public java.lang.String prettyPrint()

Description copied from interface: IPatternMatch

Prints the list of parameter-value pairs.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

specification

public Param2containmentQuerySpecification specification()

Returns:

the pattern for which this is a match.

newEmptyMatch

public static Param2containmentMatch newEmptyMatch()

Returns an empty, mutable match. Fields of the mutable match can be filled to create a partial match, usable as matcher input.

Returns:

the empty match.

newMutableMatch

public static Param2containmentMatch newMutableMatch(java.lang.Object pSource,
                                                     java.lang.Object pTarget,
                                                     Trace pTrace,
                                                     Containment pContainment)

Returns a mutable (partial) match. Fields of the mutable match can be filled to create a partial match, usable as matcher input.

Parameters:

pSource - the fixed value of pattern parameter source, or null if not bound.

pTarget - the fixed value of pattern parameter target, or null if not bound.

pTrace - the fixed value of pattern parameter trace, or null if not bound.

pContainment - the fixed value of pattern parameter containment, or null if not bound.

Returns:

the new, mutable (partial) match object.

newMatch

public static Param2containmentMatch newMatch(java.lang.Object pSource,
                                              java.lang.Object pTarget,
                                              Trace pTrace,
                                              Containment pContainment)

Returns a new (partial) match. This can be used e.g. to call the matcher with a partial match.

The returned match will be immutable. Use newEmptyMatch() to obtain a mutable match object.

Parameters:

pSource - the fixed value of pattern parameter source, or null if not bound.

pTarget - the fixed value of pattern parameter target, or null if not bound.

pTrace - the fixed value of pattern parameter trace, or null if not bound.

pContainment - the fixed value of pattern parameter containment, or null if not bound.

Returns:

the (partial) match object.
