getPresentableText

public java.lang.String getPresentableText()

Description copied from class: PsiType

Returns text of this type that can be presented to user.

Specified by:

getPresentableText in class PsiType

getCanonicalText

public java.lang.String getCanonicalText()

Specified by:

getCanonicalText in class PsiType

getInternalCanonicalText

public java.lang.String getInternalCanonicalText()

Specified by:

getInternalCanonicalText in class PsiType

getResolveScope

public GlobalSearchScope getResolveScope()

Description copied from class: PsiType

Returns the scope in which the reference to the underlying class of a class type is searched.

Specified by:

getResolveScope in class PsiType

Returns:

the resolve scope instance, or null if the type is a primitive or an array of primitives.

getSuperTypes

@NotNull
public PsiType[] getSuperTypes()

Description copied from class: PsiType

Returns the list of superclass types for a class type.

Specified by:

getSuperTypes in class PsiType

Returns:

the array of superclass types, or an empty array if the type is not a class type.

equalsToText

public boolean equalsToText(java.lang.String text)

Description copied from class: PsiType

Checks if the specified string is equivalent to the canonical text of the type.

Specified by:

equalsToText in class PsiType

Parameters:

text - the text to compare with.

Returns:

true if the string is equivalent to the type, false otherwise

getManager

public PsiManager getManager()

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

getBound

public PsiType getBound()

Use this method to obtain a bound of wildcard type.

Returns:

null if unbounded, a bound otherwise.

accept

public <A> A accept(PsiTypeVisitor<A> visitor)

Description copied from class: PsiType

Passes the type to the specified visitor.

Specified by:

accept in class PsiType

Parameters:

visitor - the visitor to accept the type.

Returns:

the value returned by the visitor.

isValid

public boolean isValid()

Description copied from class: PsiType

Checks if the type is currently valid.

Specified by:

isValid in class PsiType

Returns:

true if the type is valid, false otherwise.

PsiElement.isValid()

isExtends

public boolean isExtends()

Returns whether this is a lower bound (? extends XXX).

Returns:

true for extends wildcards, false for super and unbounded wildcards.

isSuper

public boolean isSuper()

Returns whether this is an upper bound (? super XXX).

Returns:

true for super wildcards, false for extends and unbounded wildcards.

getExtendsBound

public PsiType getExtendsBound()

A lower bound that this wildcard imposes on type parameter value.
That is:

• for ? extends XXX: XXX
• for ? super XXX: java.lang.Object
• for ?: java.lang.Object

Returns:

PsiType representing a lower bound. Never returns null.

getSuperBound

public PsiType getSuperBound()

An upper bound that this wildcard imposes on type parameter value.
That is:

• for ? extends XXX: null type
• for ? super XXX: XXX
• for ?: null type

Returns:

PsiType representing an upper bound. Never returns null.
