Example 1 with QualifiedNameExpr

use of com.github.antlrjavaparser.api.expr.QualifiedNameExpr in project spring-roo by spring-projects.

the class JavaParserUtils method getJavaType.

/**
 * Resolves the effective {@link JavaType} a {@link NameExpr} represents.
 * <p>
 * You should use {@link #getJavaType(CompilationUnitServices, Type, Set)}
 * where possible so that type arguments are preserved (a {@link NameExpr}
 * does not contain type arguments).
 * <p>
 * A name expression can be either qualified or unqualified.
 * <p>
 * If a name expression is qualified and the qualification starts with a
 * lowercase letter, that represents the fully-qualified name. If the
 * qualification starts with an uppercase letter, the package name is
 * prepended to the qualifier.
 * <p>
 * If a name expression is unqualified, the imports are scanned. If the
 * unqualified name expression is found in the imports, that import
 * declaration represents the fully-qualified name. If the unqualified name
 * expression is not found in the imports, it indicates the name to find is
 * either in the same package as the qualified name expression, or the type
 * relates to a member of java.lang. If part of java.lang, the fully
 * qualified name is treated as part of java.lang. Otherwise the compilation
 * unit package plus unqualified name expression represents the fully
 * qualified name expression.
 *
 * @param compilationUnitServices for package management (required)
 * @param nameToFind to locate (required)
 * @param typeParameters names to consider type parameters (can be null if
 *            there are none)
 * @return the effective Java type (never null)

/**
 * Recognises {@link Expression}s of type {@link FieldAccessExpr} and
 * {@link ClassExpr} and automatically imports them if required, returning
 * the correct {@link Expression} that should subsequently be used.
 * <p>
 * Even if an {@link Expression} is not resolved by this method into a type
 * and/or imported, the method guarantees to always return an
 * {@link Expression} that the caller can subsequently use in place of the
 * passed {@link Expression}. In practical terms, the {@link Expression}
 * passed to this method will be returned unless the type was already
 * imported, just imported, or represented a java.lang type.
 *
 * @param targetType the compilation unit target type (required)
 * @param imports the existing imports (required)
 * @param value that expression, which need not necessarily be resolvable to
 *            a type (required)
 * @return the expression to now use, as appropriately resolved (never
 *         returns null)
