Struct SystemTypeIndex

Provides a unique id for system types as well as quick lookup information about the system type itself. This value is fully deterministic at runtime but should not be considered deterministic across builds and thus should not be serialized.

Namespace: Unity.Entities

Assembly: Unity.Entities.dll

Syntax

public struct SystemTypeIndex

Fields

Name	Description
Value	Raw value used to identify System types at runtime. This value should not be serialized as it is not guaranteed to be deterministic across builds (but is during runtime).

Properties

Name	Description
Flags	Type flags stored in Value
Index	Zero-based index for the SystemTypeIndex stored in Value (the type index with no flags).
IsGroup	The system type inherits from ComponentSystemGroup
IsISystemStartStop	The system type inherits from ISystemStartStop
IsManaged	The system type is a class and inherits from ComponentSystemBase.
Null	An invalid SystemTypeIndex which does not map to a valid System type.

Methods

Name	Description
CompareTo(SystemTypeIndex)	Compare this SystemTypeIndex against a given one
Equals(object)	SystemTypeIndex instances are equal if they refer to the same system type.
Equals(SystemTypeIndex)	SystemTypeIndex instances are equal if they refer to the same system type.
GetHashCode()	A hash used for comparisons.
ToFixedString()	Provides a Burst compatible debugging string.
ToString()	Provides a debugging string.

Operators

Name	Description
operator ==(SystemTypeIndex, SystemTypeIndex)	SystemTypeIndex instances are equal if they refer to the same system type.
operator >(SystemTypeIndex, SystemTypeIndex)	Evaluates if one SystemTypeIndex is greater than the other.
operator >=(SystemTypeIndex, SystemTypeIndex)	Evaluates if one SystemTypeIndex is greater than or equal to the other.
implicit operator SystemTypeIndex(int)	Implicit conversion from an int to a SystemTypeIndex.
implicit operator int(SystemTypeIndex)	Implicit conversion from SystemTypeIndex to an int.
operator !=(SystemTypeIndex, SystemTypeIndex)	SystemTypeIndex instances are equal if they refer to the same system type.
operator <(SystemTypeIndex, SystemTypeIndex)	Evaluates if one SystemTypeIndex is less than the other.
operator <=(SystemTypeIndex, SystemTypeIndex)	Evaluates if one SystemTypeIndex is less than or equal to the other.
