Constructor Details

PgConstraintCheck

public PgConstraintCheck(String name)

Creates a new PostgreSQL CHECK constraint.

Parameters:

name - constraint name

Method Details

setInherit

public void setInherit(boolean isInherit)

setExpression

public void setExpression(String expression)

getDefinition

public String getDefinition()

Description copied from interface: IConstraint

Gets the SQL definition of this constraint.

Returns:

the constraint definition

compare

public boolean compare(PgStatement obj)

Description copied from class: PgStatement

This method does not account for nested child PgStatements. Shallow version of PgStatement.equals(Object)

Overrides:

compare in class PgConstraint

computeHash

public void computeHash(Hasher hasher)

Description copied from interface: IHashable

Computes the hash of the implementing object using the provided hasher. The implementation should call appropriate put methods on the hasher for all fields that should contribute to the hash value.

Specified by:

computeHash in interface IHashable

Overrides:

computeHash in class PgConstraint

Parameters:

hasher - the hasher instance to use for hash computation

getErrorCode

public String getErrorCode()
