getExtensionReceiverParameter

@Nullable
public ReceiverParameterDescriptor getExtensionReceiverParameter()

Specified by:

getExtensionReceiverParameter in interface CallableDescriptor

getDispatchReceiverParameter

@Nullable
public ReceiverParameterDescriptor getDispatchReceiverParameter()

Specified by:

getDispatchReceiverParameter in interface CallableDescriptor

getOverriddenDescriptors

@NotNull
public java.util.Collection<? extends FunctionDescriptor> getOverriddenDescriptors()

Description copied from interface: FunctionDescriptor

This method should be used with q Wgreat care, because if descriptor is substituted one, calling 'getOverriddenDescriptors' may force lazy computation, that's unnecessary in most cases. So, if 'getOriginal().getOverriddenDescriptors()' is enough for you, please use it instead.

Specified by:

getOverriddenDescriptors in interface CallableDescriptor

Specified by:

getOverriddenDescriptors in interface CallableMemberDescriptor

Specified by:

getOverriddenDescriptors in interface FunctionDescriptor

getModality

@NotNull
public Modality getModality()

isHiddenToOvercomeSignatureClash

public boolean isHiddenToOvercomeSignatureClash()

Specified by:

isHiddenToOvercomeSignatureClash in interface FunctionDescriptor

true if descriptor signature clashed with some other signature and it's supposed to be legal See java.nio.CharBuffer

setOverriddenDescriptors

public void setOverriddenDescriptors(@NotNull
                                     java.util.Collection<? extends CallableMemberDescriptor> overriddenDescriptors)

getValueParameters

@NotNull
public java.util.List<ValueParameterDescriptor> getValueParameters()

Specified by:

hasStableParameterNames

public boolean hasStableParameterNames()

Description copied from interface: CallableDescriptor

Kotlin functions always have stable parameter names that can be reliably used when calling them with named arguments. Functions loaded from platform definitions (e.g. Java binaries or JS) may have unstable parameter names that vary from one platform installation to another. These names can not be used reliably for calls with named arguments.

Specified by:

hasStableParameterNames in interface CallableDescriptor

hasSynthesizedParameterNames

public boolean hasSynthesizedParameterNames()

Description copied from interface: CallableDescriptor

Sometimes parameter names are not available at all (e.g. Java binaries with not enough debug information). In this case, getName() returns synthetic names such as "p0", "p1" etc.

Specified by:

hasSynthesizedParameterNames in interface CallableDescriptor

getReturnType

public KotlinType getReturnType()

Description copied from interface: CallableDescriptor

Method may return null for not yet fully initialized object or if error occurred.

Specified by:

Specified by:

getOriginal in interface CallableDescriptor

Specified by:

Specified by:

Specified by:

getOriginal in interface DeclarationDescriptorWithSource

Specified by:

getOriginal in interface FunctionDescriptor

Overrides:

getOriginal in class DeclarationDescriptorNonRootImpl

Returns:

The descriptor that corresponds to the original declaration of this element. A descriptor can be obtained from its original by substituting type arguments (of the declaring class or of the element itself). returns this object if the current descriptor is original itself
