Nested Class Summary

Modifier and Type	Interface	Description
`static interface`	`Signature.ArrayTypeSig`	Models the signature of an array type.
`static interface`	`Signature.BaseTypeSig`	Models the signature of a primitive type (JLS 4.2) or void.
`static interface`	`Signature.ClassTypeSig`	Models the signature of a possibly-parameterized class or interface type.
`static interface`	`Signature.RefTypeSig`	Models the signature of a reference type, which may be a class, interface, type variable, or array type.
`static interface`	`Signature.ThrowableSig`	Marker interface for a signature for a throwable type.
`static interface`	`Signature.TypeArg`	Models a type argument, an argument to a type parameter.
`static interface`	`Signature.TypeParam`	Models a signature for a type parameter of a generic class, interface, method, or constructor, which introduces a type variable.
`static interface`	`Signature.TypeVarSig`	Models the signature of a type variable.

Method Summary

Modifier and Type	Method	Description
`static Signature`	`of(ClassDesc classDesc)`	Returns a Java type signature from a field descriptor.
`static Signature`	`parseFrom(String javaTypeSignature)`	Parses a Java type signature from a raw string.
`String`	`signatureString()`	Returns the raw signature string.

Method Details

signatureString

String signatureString()

Returns the raw signature string.

Returns:: the raw signature string

parseFrom

static Signature parseFrom(String javaTypeSignature)

Parses a Java type signature from a raw string.

Parameters:: javaTypeSignature - raw Java type signature string
Returns:: a Java type signature
Throws:: IllegalArgumentException - if the string is not a valid Java type signature string

of

static Signature of(ClassDesc classDesc)

Returns a Java type signature from a field descriptor. The returned signature represents a reifiable type (JLS 4.7).

Parameters:: classDesc - the symbolic description of the Java type
Returns:: a Java type signature from a field descriptor
