Enum Constant Summary

ALL
Retrieves all the identification variables declared in the declaration portion of the expression, which is either in the FROM clause of a SELECT query or DELETE query or in the UPDATE query.

COLLECTION
Only retrieves the identification variables that map a path expression defined in a JOIN expression or in a IN expression.

LEFT
Only retrieves the identification variables that have been declared to the left of the expression requested them, both range and collection type variables are collected.

LEFT_COLLECTION
Only retrieves the identification variables that map a path expression defined in a JOIN expression or in a IN expression but that have been declared to the left of the expression requested them.

NONE
Simply indicate the identification variables should not be collected.

RESULT_VARIABLE
Retrieves the result variables that have been defined in the SELECT clause.

public static final ContentAssistVisitor.IdentificationVariableType ALL

Retrieves all the identification variables declared in the declaration portion of the expression, which is either in the FROM clause of a SELECT query or DELETE query or in the UPDATE query.

COLLECTION

public static final ContentAssistVisitor.IdentificationVariableType COLLECTION

Only retrieves the identification variables that map a path expression defined in a JOIN expression or in a IN expression.

LEFT

public static final ContentAssistVisitor.IdentificationVariableType LEFT

Only retrieves the identification variables that have been declared to the left of the expression requested them, both range and collection type variables are collected.

LEFT_COLLECTION

public static final ContentAssistVisitor.IdentificationVariableType LEFT_COLLECTION

Only retrieves the identification variables that map a path expression defined in a JOIN expression or in a IN expression but that have been declared to the left of the expression requested them.

NONE

public static final ContentAssistVisitor.IdentificationVariableType NONE

Method Detail

values

public static ContentAssistVisitor.IdentificationVariableType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ContentAssistVisitor.IdentificationVariableType c : ContentAssistVisitor.IdentificationVariableType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ContentAssistVisitor.IdentificationVariableType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
