public class FieldConfig
extends SimplePropertyConfig

A field is used to define the smallest physical part of a stream. Fields are combined to form segments and records.

Unless bound is set to false, a field is bound to a property of its closest parent bean object.

Position must be set for all fields in record, or for none of them. If not set, position is determined based on the order in which the fields are added to the record.

Constructor Detail

FieldConfig

public FieldConfig()

Constructs a new FieldConfig.

Method Detail

getComponentType

public char getComponentType()

Description copied from class: ComponentConfig

Returns the component type.

Specified by:

getComponentType in class ComponentConfig

Returns:

one of ComponentConfig.GROUP, ComponentConfig.RECORD, ComponentConfig.SEGMENT, ComponentConfig.FIELD, ComponentConfig.CONSTANT or ComponentConfig.WRAPPER

getDefault

public String getDefault()

Returns the textual representation of the default value for this field when the field is not present or empty during unmarshalling. May be null.

Returns:

the default value (as text)

setDefault

public void setDefault(String text)

Sets the textual representation of the default value of this field when the field is not present or empty during unmarshalling. May be null.

Parameters:

text - the default value (as text)

getMinLength

public Integer getMinLength()

Returns the minimum length of this field in characters, or null if a minimum length should not be enforced.

Returns:

the minimum length, or null if not enforced

setMinLength

public void setMinLength(Integer minLength)

Sets the minimum length of this field in characters, or null if a minimum length should not be enforced.

Parameters:

minLength - the minimum length, or null if not enforced

getMaxLength

public Integer getMaxLength()

Returns the maximum length of this field in characters. Returns null if a maximum length will not be enforced.

Returns:

the maximum length, or null if not enforced

setMaxLength

public void setMaxLength(Integer maxLength)

Sets the maximum length of this field in characters. Set to null if a maximum length should not be enforced.

Parameters:

maxLength - the maximum length, or null if not enforced

isTrim

public boolean isTrim()

Returns whether field text should be trimmed before validation and type conversion.

Returns:

true if field text should be trimmed

setTrim

public void setTrim(boolean trim)

Sets whether field text should be trimmed before validation and type conversion.

Parameters:

trim - true if field text should be trimmed

getLiteral

public String getLiteral()

Returns the static text for this field, or null if the field text is not static. If set, unmarshalled field text must match the literal text, and likewise, the literal text is always marshalled for this field.

Returns:

the literal text of the field

setLiteral

public void setLiteral(String literal)

Sets the static text for this field. If set, unmarshalled field text must match the literal text, and likewise, the literal text is always marshalled for this field.

Parameters:

literal - the literal text of the field

getRegex

public String getRegex()

Returns the regular expression pattern for validating the field text during unmarshalling. Field text is only validated using the regular expression after trimming (if enabled) and when its not the empty string.

Returns:

the regular expression pattern

setRegex

public void setRegex(String pattern)

Sets the regular expression pattern for validating the field text during unmarshalling. Field text is only validated using the regular expression after trimming (if enabled) and when its not the empty string.

Parameters:

pattern - the regular expression pattern

isRequired

public boolean isRequired()

Returns true if this field is required when unmarshalled. Required fields must have at least one character (after trimming, if enabled). If this field is not required and no text is parsed from the input stream, no further validations are performed.

Returns:

true if this field is required

setRequired

public void setRequired(boolean required)

Set to true if this field is required when unmarshalled. Required fields must have at least one character (after trimming, if enabled). If this field is not required and no text is parsed from the input stream, no further validations are performed.

Parameters:

required - true if this field is required

getLength

public Integer getLength()

Returns the length of this field in characters. Applies to fixed length and padded fields. May return -1 (aka 'unbounded'), for the last field in a fixed length record to indicate it is not padded and of variable length.

Returns:

the length of this field

Sets the length of this field in characters. Applies to fixed length and padded fields.

Parameters:

length - the length of this field
