Constructor Details

ParameterizedTypeInfoImpl

public ParameterizedTypeInfoImpl(TypeInfo ownerType,
 TypeInfo rawType,
 List<TypeInfo> params)

Method Details

asClass

public Class<?> asClass()

Description copied from interface: TypeInfo

Get the Class object represented by this TypeInfo. For a Type object, the TypeInfo object created from the Type object should return the exact same class as the one after Java erased its generic type info

Specified by:

asClass in interface TypeInfo

is

public boolean is(Class<?> c)

Specified by:

is in interface TypeInfo

Returns:

true if this TypeInfo represents the same class as the Class parameter, false otherwise

ownerType

public TypeInfo ownerType()

Specified by:

ownerType in interface ParameterizedTypeInfo

See Also:

• ParameterizedType.getOwnerType()

param

public TypeInfo param(int index)

Description copied from interface: TypeInfo

Example:

1. for Map<String, Integer>, param(-1) == TypeInfo.NONE, param(0) == TypeInfo.STRING, param(1) == TypeInfo.INT, param(2) == TypeInfo.NONE

2. for Map (raw usage of generic class) or Integer (not generic class), param(anyNumberHere) == TypeInfo.NONE

Specified by:

param in interface ParameterizedTypeInfo

Specified by:

param in interface TypeInfo

Returns:

the actual type parameter at provided index, or TypeInfo.NONE if:

1. index not in valid range, or

2. the TypeInfo itself is not representing a ParameterizedType

See Also:

• ParameterizedTypeInfo.params()

extractConsolidationMapping

public Map<VariableTypeInfo,TypeInfo> extractConsolidationMapping(TypeInfoFactory factory)

Description copied from interface: ParameterizedTypeInfo

Extract consolidation mapping based on ParameterizedTypeInfo.params() and Class.getTypeParameters()

Example: type is List<String>, calling ((ParameterizedTypeInfo) type).extractConsolidationMapping(TypeInfoFactory.GLOBAL) will give E -> String, where the E the type variable declared by List

Specified by:

extractConsolidationMapping in interface ParameterizedTypeInfo

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object object)

Overrides:

equals in class Object

rawType

public TypeInfo rawType()

Specified by:

rawType in interface ParameterizedTypeInfo

See Also:

• ParameterizedType.getRawType()

params

public List<TypeInfo> params()

Specified by:

params in interface ParameterizedTypeInfo

See Also:

• ParameterizedType.getActualTypeArguments()

newArray

public Object newArray(int length)

Description copied from interface: TypeInfo

get an array whose element type is the caller TypeInfo

Specified by:

newArray in interface TypeInfo

Overrides:

newArray in class TypeInfoBase

consolidate

public TypeInfo consolidate(Map<VariableTypeInfo,TypeInfo> mapping)

Specified by:

consolidate in interface TypeInfo
