Interface Summary

Interface	Description
BasicUtil	This is the interface for a collection of utility functions for very general operations especially for dealing with Arrays.
Builder<T>	This is the generic interface for a builder.
CharIterator	This is the interface for an Iterator of primitive char values.
CompilerWarnings	This type contains the available string constants for the SuppressWarnings annotation.
Datatype	This is the interface for a datatype.
DatatypeDescriptor<T>	This is the interface to describe a Datatype.
DatatypeDescriptorManager	This is the interface for a manager of DatatypeDescriptors for all supported Datatypes.
DatatypeDetector	This is the interface to detect if some type is a Datatype.
DatatypeSegmentDescriptor<T,V>	This is the interface for a descriptor of a segment.
EnumDefinition<TYPE,CATEGORY>	This is the interface for the definition of an EnumType.
EnumProvider	This is the interface for a generic provider of enumerations.
EnumType<V>	This is the interface for a particular enumeration.
EnumTypeWithCategory<V,CATEGORY>	This is the interface for an EnumType that has a category.
EnvironmentDetector	This is the interface for a detector of the environment.
EqualsChecker<VALUE>	This (functional) interface allows to implement an external function to check if two objects are considered as equal independent from the objects equals method.
Formatter<V>	This is the interface for a formatter that allows to format a given object of a generic type.
HashCodeFunction<VALUE>	This (functional) interface allows to implement an external function to calculate the hash code of an object of the type <VALUE>.
LocalizableFormatter<V>	This is the interface for a Formatter that is localizable.
Message	This is the interface for a message that gets displayed to an end-user.
SimpleDatatype<V>	This is the interface for a simple Datatype, that can be represented by a single standard value.
StringSyntax	This interface defines the syntax for a decoding and encoding values from/to String.
StringUtil	This is the interface for a collection of utility functions that help with String handling and manipulation.
SystemInformation	This is the interface for a data-object containing structured of an operating system.
SystemUtil	This is the interface for a collection of utility functions that help to deal with things specific for the operating system running this java virtual machine.
Variant	This interface only exists for documentation of the concept of a variant.
Visitor<V>	This is the interface for a generic visitor that may Visitor.visit(Object) values of a specific type.

Class Summary

Class	Description
AbstractDatatype	This is the abstract base implementation of a simple Datatype.
AbstractEqualsChecker<VALUE>	This is the abstract base implementation of EqualsChecker.
AbstractHashCodeFunction<VALUE>	This is the abstract base implementation of HashCodeFunction.
AbstractSimpleDatatype<V>	This is the abstract base implementation of a simple Datatype.
AbstractSimpleDatatypeBase<V>	This is the abstract base implementation of a simple Datatype.
ComparatorHelper	This class contains the implementation of CompareOperator.eval(Object, Object) for Comparable arguments.
EqualsCheckerIsEqual	This is an implementation of EqualsChecker that simply delegates to Object.equals(Object).
EqualsCheckerIsSame	This is an implementation of EqualsChecker that simply checks if two objects are same (identical instances, checked via == operator).
GenericBean<TYPE>	This class is a simple java bean that has one generic property named value.
GwtHelper	This class is used as indirection for code that is NOT GWT compatible.
HashCodeFunctionDefault	This is the default implementation of HashCodeFunction.
HashCodeFunctionSystemIdentity	This is an implementation of HashCodeFunction that delegates to System.identityHashCode(Object) and conforms to EqualsCheckerIsSame.
Password	This is the Datatype used to store a simple password as String.
StringTokenizer	This is a rewrite of the awkward StringTokenizer provided by the JDK.

Enum Summary

Enum	Description
Alignment	This enum contains the available values for the alignment of an object.
BooleanEnum	A BooleanEnum represents a Boolean as enum type.
CompareOperator	A CompareOperator represents a function that compares two given values.

Package net.sf.mmm.util.lang.api Description

Provides the API for utilities of general purpose.

Util Lang API

This is the package of very general utilities (analog to java.lang). This package contains utilities for dealing with the basic types Object, String, and with arrays.
