substitute

public PsiType substitute(PsiTypeParameter typeParameter)

Description copied from interface: PsiSubstitutor

Returns a mapping that this substitutor contains for a given type parameter. Does not perform bounds promotion

Specified by:

substitute in interface PsiSubstitutor

Parameters:

typeParameter - the parameter to return the mapping for.

Returns:

the mapping for the type parameter, or null for a raw type.

substitute

public PsiType substitute(PsiType type)

Description copied from interface: PsiSubstitutor

Substitutes type parameters occurring in type with their values. If value for type parameter is null, appropriate erasure is returned.

Specified by:

substitute in interface PsiSubstitutor

Parameters:

type - the type to substitute the type parameters for.

Returns:

the result of the substitution.

substituteWithBoundsPromotion

public PsiType substituteWithBoundsPromotion(PsiTypeParameter typeParameter)

Specified by:

substituteWithBoundsPromotion in interface PsiSubstitutor

put

public PsiSubstitutor put(PsiTypeParameter classParameter,
                          PsiType mapping)

Description copied from interface: PsiSubstitutor

Creates a substitutor instance which provides the specified parameter to type mapping in addition to mappings contained in this substitutor.

Specified by:

put in interface PsiSubstitutor

Parameters:

classParameter - the parameter which is mapped.

mapping - the type to which the parameter is mapped.

Returns:

the new substitutor instance.

putAll

public PsiSubstitutor putAll(PsiClass parentClass,
                             PsiType[] mappings)

Description copied from interface: PsiSubstitutor

Creates a substitutor instance which maps the type parameters of the specified class to the specified types in addition to mappings contained in this substitutor.

Specified by:

putAll in interface PsiSubstitutor

Parameters:

parentClass - the class whose parameters are mapped.

mappings - the types to which the parameters are mapped.

Returns:

the new substitutor instance.

putAll

public PsiSubstitutor putAll(PsiSubstitutor another)

Description copied from interface: PsiSubstitutor

Creates a substitutor instance containing all mappings from this substitutor and the specified substitutor.

Specified by:

putAll in interface PsiSubstitutor

Parameters:

another - the substitutor to get the mappings from.

Returns:

the new substitutor instance.

putAll

public PsiSubstitutor putAll(java.util.Map<? extends PsiTypeParameter,? extends PsiType> map)

Description copied from interface: PsiSubstitutor

Creates a substitutor instance containing all mappings from this substitutor and the specified map.

Specified by:

putAll in interface PsiSubstitutor

Parameters:

map - a map which contains additional mappings

Returns:

the new substitutor instance.

getSubstitutionMap

public java.util.Map<PsiTypeParameter,PsiType> getSubstitutionMap()

Description copied from interface: PsiSubstitutor

Returns the map from type parameters to types used for substitution by this substitutor.

Specified by:

getSubstitutionMap in interface PsiSubstitutor

Returns:

the substitution map instance.

isValid

public boolean isValid()

Description copied from interface: PsiSubstitutor

Checks if all types which the substitutor can substitute are valid.

Specified by:

isValid in interface PsiSubstitutor

Returns:

true if all types are valid, false otherwise.

See Also:

PsiType.isValid()

ensureValid

public void ensureValid()

Description copied from interface: PsiSubstitutor

If this substitutor is not valid, throws an exception with some diagnostics

Specified by:

ensureValid in interface PsiSubstitutor

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
