An import declaration allows a named type or a static member to be referred to by a simple name instead of a fully qualified name. The XL programming language defines four kinds of import declarations:

Import Declarations

[8]	ImportDeclaration	`::=`	SingleTypeImportDeclaration \| TypeImportOnDemandDeclaration \| SingleStaticImportDeclaration \| StaticImportOnDemandDeclaration
[9]	SingleTypeImportDeclaration	`::=`	`import` Name ';'
[10]	TypeImportOnDemandDeclaration	`::=`	`import` Name '.' '*' ';'
[11]	SingleStaticImportDeclaration	`::=`	`import` `static` Name '.' Identifier ';'
[12]	StaticImportOnDemandDeclaration	`::=`	`import` `static` Name '.' '*' ';'

The first two kinds, single-type-import and type-import-on-demand declarations, are already known from the Java programming language. Thus, they are not explained here. The last two kinds, single-static-import and static-import-on-demand declarations, have been defined in the Java Language Specification, Third Edition, and are defined for the XL programming language, too.

A single-static-import declaration imports all accessible static members with the given name from the given type. For the details see the Java Language Specification, Third Edition.

A static-import-on-demand declaration imports all accessible static members declared in the given type as needed. For the details see the Java Language Specification, Third Edition.
