Method Details

getStatementType

public DbObjType getStatementType()

Description copied from interface: IStatement

Gets the type of this database object.

Specified by:

getStatementType in interface IStatement

Returns:

the database object type

setCache

public void setCache(String cache)

getRelationColumns

public Stream<Pair<String,String>> getRelationColumns()

Description copied from interface: IRelation

Gets the columns of this relation as name-type pairs.

Specified by:

getRelationColumns in interface IRelation

Returns:

a stream of column name and type pairs

setCycle

public void setCycle(boolean cycle)

setMinMaxInc

public abstract void setMinMaxInc(long inc,
 Long max,
 Long min,
 String dataType,
 long precision)

Sets the minimum, maximum, and increment values for this sequence.

Parameters:

inc - the increment value

max - the maximum value

min - the minimum value

dataType - the data type of the sequence

precision - the precision for numeric types

setStartWith

public void setStartWith(String startWith)

setDataType

public void setDataType(String dataType)

getDataType

public String getDataType()

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 PgStatement

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

Parameters:

hasher - the hasher instance to use for hash computation

shallowCopy

public AbstractSequence shallowCopy()

Description copied from class: PgStatement

Copies all object properties into a new object and leaves all its children empty.

Specified by:

shallowCopy in class PgStatement

Returns:

shallow copy of a DB object.

fillSequenceBody

public abstract void fillSequenceBody(StringBuilder sbSQL)

Fills the sequence body SQL definition.

Parameters:

sbSQL - the StringBuilder to append the sequence body to

getContainingSchema

public AbstractSchema getContainingSchema()

Description copied from interface: ISearchPath

Gets the schema that contains this object.

Specified by:

getContainingSchema in interface ISearchPath

Returns:

the containing schema
