Record Class Field

java.lang.Object

java.lang.Record

dev.omnist.schema.Field

Record Components:

label - the field label; must not be null

type - the field type; must not be null

min - the minimum occurrence count; must be >= 0

max - the maximum occurrence count; null means unbounded; if non-null, must be >= min

public record Field(String label, Type type, int min, Integer max)
extends Record

An immutable field declaration within a Record definition (omnist-spec §5.4).

A field captures:

• a label — the JSON/OML key name as a quoted string in OSD
• a type — a scalar type, a Type.Ref to another record, or Type.Any
• cardinality bounds [min, max] — minimum and maximum occurrence count per node; max == null means unbounded

The default cardinality when omitted in OSD is [1, 1] (exactly one occurrence).

Constructor Details

Field

public Field(String label,
 Type type,
 int min,
 Integer max)

Compact constructor that enforces label/type non-null and cardinality invariants.

Throws:

NullPointerException - if label or type is null

IllegalArgumentException - if min is negative, or if max is non-null and less than min

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

label

public String label()

Returns the value of the label record component.

Returns:

the value of the label record component

type

public Type type()

Returns the value of the type record component.

Returns:

the value of the type record component

min

public int min()

Returns the value of the min record component.

Returns:

the value of the min record component

max

public Integer max()

Returns the value of the max record component.

Returns:

the value of the max record component
