Method Detail

createField

protected static DBFField createField(java.io.DataInput in)
                               throws java.io.IOException

Creates a DBFField object from the data read from the given DataInputStream. The data in the DataInputStream object is supposed to be organised correctly and the stream "pointer" is supposed to be positioned properly.

Parameters:

in - DataInputStream

Returns:

Returns the created DBFField object.

Throws:

java.io.IOException - If any stream reading problems occures.

write

protected void write(java.io.DataOutput out)
              throws java.io.IOException

Writes the content of DBFField object into the stream as per DBF format specifications.

Throws:

java.io.IOException - if any stream related issues occur.

getName

public java.lang.String getName()

Returns the name of the field.

Returns:

Name of the field as String.

getDataType

public byte getDataType()

Returns the data type of the field.

Returns:

Data type as byte.

getFieldLength

public int getFieldLength()

Returns field length.

Returns:

field length as int.

getDecimalCount

public int getDecimalCount()

Returns the decimal part. This is applicable only if the field type if of numeric in nature. If the field is specified to hold integral values the value returned by this method will be zero.

Returns:

decimal field size as int.

setFieldName

public void setFieldName(java.lang.String value)

Deprecated. This method is depricated as of version 0.3.3.1 and is replaced by setName( String).

setName

public void setName(java.lang.String value)

Sets the name of the field.

Since:

0.3.3.1

setDataType

public void setDataType(byte value)

Sets the data type of the field.

setFieldLength

public void setFieldLength(int value)

Length of the field. This method should be called before calling setDecimalCount().

setDecimalCount

public void setDecimalCount(int value)

Sets the decimal place size of the field. Before calling this method the size of the field should be set by calling setFieldLength().
