Constructor Details

PgView

public PgView(String name)

Creates a new PostgreSQL view.

Parameters:

name - view name

Method Details

addColumnDefaultValue

public void addColumnDefaultValue(String columnName,
 String defaultValue)

Adds/replaces column default value specification.

Parameters:

columnName - column name

defaultValue - default value expression

removeColumnDefaultValue

public void removeColumnDefaultValue(String columnName)

Removes column default value specification.

Parameters:

columnName - column name to remove default from

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 AbstractPgView

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 AbstractPgView

Parameters:

hasher - the hasher instance to use for hash computation
