Method Detail

getMax

public int getMax()

get the max display width for the field

Returns:

int width

getNullable

public boolean getNullable()

Can this field be null

Returns:

boolean true if can be null.

getType

public int getType()

return column type as generated by getColumnType from ResultSet

Returns:

int

getName

public java.lang.String getName(boolean qualify)

get the name of the field. We don't support quoting in this method so it can be optimised for speed. Use addName when constructing a query where quoting may be required.

Parameters:

qualify -

Returns:

String field name

addName

public java.lang.StringBuilder addName(java.lang.StringBuilder sb,
                                       boolean qualify,
                                       boolean quote)

Add the field name to a StringBuilder

Parameters:

sb - StringBuilder to append to

qualify - boolean Should field name be qualified with table

quote - boolean apply quoting for SQL fragment

Returns:

modified StringBuilder

isNumeric

public boolean isNumeric()

isData

public boolean isData()

getReferencedTable

public java.lang.String getReferencedTable()

Get the tag that will-be/has-been used to create the referenced IndexedTypeProducer. if the producer has been installed explicitly this will return null because there is no guarantee the producers tag can be used to construct a TypeProducer. So always use getTypeProducer() in preference to constructing via this tag.

Returns:

constructor tag

getTypeProducer

public TypeProducer getTypeProducer()

isString

public boolean isString()

isDate

public boolean isDate()

isBoolean

public boolean isBoolean()

isIndexed

public boolean isIndexed()

isUnique

public boolean isUnique()

Is this a unique reference where there is a 1-1 mapping between records in the source and destination table.

Returns:

setUnique

public void setUnique(boolean value)

getForeignKeyName

public java.lang.String getForeignKeyName()

isReference

public boolean isReference()

getTag

public java.lang.String getTag()

get the tag used to store this field in the record. Normally the field name unless renaming taking place

Returns:

isTruncate

public boolean isTruncate()

setTruncate

public void setTruncate(boolean truncate)
