Constructor Detail

Int32Type

public Int32Type()

Creates a new Int32Type.

Int32Type

public Int32Type(int lowerLimit,
                 int upperLimit)

Creates a new Int32Type with limits.

Method Detail

getLowerLimit

public final int getLowerLimit()

Returns the lower limit.

getUpperLimit

public final int getUpperLimit()

Returns the upper limit.

getJavaClass

public final java.lang.Class<java.lang.Integer> getJavaClass()

Returns the Java class instance that is being used for the values of this type.

getMaxFieldSize

public int getMaxFieldSize()

Returns the maximum field size required to enter a value of this type.

This is the maximum number of characters required to enter a string representation of all valid values of this type. The typical size of an input field may be much smaller.

Specified by:

getMaxFieldSize in interface Type

Overrides:

getMaxFieldSize in class ScalarType

checkConstraints

public void checkConstraints(Record rec,
                             Column column)
                      throws PObjConstraintException

Checks all constraints imposed on values of this type.

Specified by:

checkConstraints in interface Type

Overrides:

checkConstraints in class ScalarType

Parameters:

rec - The record which contains column.

column - The column of rec which has this type.

Throws:

PObjConstraintException - when any constraint imposed on values of this type is not fulfilled.

checkSyntax

public void checkSyntax(java.lang.String value)
                 throws PObjSyntaxException

Specified by:

checkSyntax in interface Type

Overrides:

checkSyntax in class ScalarType

Throws:

PObjSyntaxException

parseNative

public java.lang.Object parseNative(java.lang.String value)
                             throws PObjSyntaxException

Parse value according to the `native' string representation of this type.

This representation is a one-to-one mapping of the type's value set to strings, without any translation based on MapItems associated with the type.

For example, an integer type's implementation would accept a value like `"1"' and translate it to an integer object, but would reject a label like `"Yes"' that may be associated with the value `1'.

Throws:

PObjSyntaxException - if value couldn't be parsed as a string representation of this type.

See Also:

Type.addMap(MapItem), Type.parse(String)

setParam

public void setParam(JdbcContainer db,
                     java.sql.PreparedStatement statm,
                     int pos,
                     java.lang.Object value)
              throws java.sql.SQLException

Sets the parameter(s) starting at startPos.

This method is the counterpart to Type.getResult(JdbcContainer,ResultSet,int) and Type.getResultInc().

Throws:

java.sql.SQLException - if any database error occurs.
