Class GenericClassSignatureParser

java.lang.Object

org.hl7.cql.model.GenericClassSignatureParser

public class GenericClassSignatureParser
extends java.lang.Object

The GenericClassSignatureParser is a convenience class for the parsing of generic signature and the creation of the corresponding CQL DataTypes, namely, GenericClassType and GenericClassProfileType. The former is used to capture the declaration of a GenericClass such as List<T>. The latter is used to capture a new type such as 'IntegerList' formed by binding types to generic parameters such as List<Integer>.

parseGenericSignature

public ClassType parseGenericSignature()

Parses a generic type declaration such as Map<K,V>.

Returns:

Generic class constructed from this definition.

handleParameterDeclaration

protected TypeParameter handleParameterDeclaration(java.lang.String parameterString)

Method handles a generic parameter declaration such as T, or T extends MyType.

Parameters:

parameterString -

Returns:

Type parameter for this parameter for this string declaration.

resolveTypeName

protected DataType resolveTypeName(java.lang.String parameterType)

Identifies the data type for the named type. If the argument is null, the return type will be null.

Parameters:

parameterType -

Returns:

The parameter's type

handleBoundType

protected DataType handleBoundType(java.lang.String boundGenericSignature)

Method resolves bound type if it exists or else creates it and adds it to the resolved type index.

Parameters:

boundGenericSignature -

Returns:

The bound type created or resolved

isValidGenericSignature

public boolean isValidGenericSignature()

Returns true if the generic signature assigned to this object is well-formed.

Returns:

True if the generic signature is valid

isValidGenericSignature

public boolean isValidGenericSignature(java.lang.String genericSignature)

Returns true if the generic signature passed as an argument is well-formed.

Parameters:

genericSignature -

Returns:

True if the generic signature is valid
